On this day: Brown, Poirier, Fall, Vincent debut; Gavitt, Dickey born; Mangurian passes; Cousy, Macauley jerseys retired

On this day, a number of Celtics debuted, former owner Harry Mangurian passed away, and Dave Gavitt was born.

On this day in Boston Celtics history, All-Star forward Jaylen Brown played his first game for the team in 2016, fittingly a 122-117 win over the Brooklyn Nets, the team who had dealt Boston the draft pick that would be used to select him.

The former Cal-Berkeley standout put up 9 points, 2 rebounds, an assist, a steal, and two blocks, with one turnover and two fouls in 19 minutes and 27 seconds of floor time for his debut performance with the Celtics. He shot 3-of-4 from the free-throw line and hit three of his four field goal attempts as well.

Perhaps surprisingly, Brown did not attempt a 3-point shot in his inaugural game in the association.
